Undefeated heavyweight puncher Deontay Wilder has served as a sparring partner for undisputed champion Wladimir Klitschko, and could be in line for the WBC title owned by Klitschko’s older brother, Vitali Klitschko.

Alexander Povetkin won the WBA’s “regular” heavyweight title when he beat Ruslan Chagaev in 2011 but the undefeated Russian says he consider himself “the real champion” until he beats RING champ Wladimir Klitschko, who he challenges on Saturday in Moscow.

Against Kertson Manswell on Saturday night, “The world is going to see why we keep saying…that Deontay Wilder is going to be America’s next heavyweight champion of the world,” said Wilder, who is 23-0, all by knockout.
